Subject: [PATCH] Drop tsched ALSA parameter for Raspberry Pi devices (#138)

Presumably the newer audio drivers in Linux 5.15/6.1 do not require this
parameter any longer. Tests on HAOS 9.5 and HAOS 10.1 with the VLC
add-on (using latest Alpine 3.17) provided mp3 and TTS playback without
dropouts (on the 3.5mm analog audio jack).
